Abstract

The invention provides zinc oxide-based nanoparticle ink. The zinc oxide-based nanoparticle ink comprises a solvent and zinc oxide-based nanoparticles uniformly dispersed in the solvent. The zinc oxide-based nanoparticle ink comprises, by mass, 0.01 to 20.00% of the zinc oxide-based nanoparticles and 80.00 to 99.99% of the solvent. The zinc oxide-based nanoparticle ink is characterized in that the solvent comprises at least one alcohol ether ester compound. The zinc oxide-based nanoparticle ink can solve the problem that the existing zinc oxide-based nanoparticle ink is not suitable for ink-jet printing and has poor film-forming quality. The invention provides an electroluminescent device. An electron transport layer of the device is prepared from the zinc oxide-based nanoparticle ink through ink-jet printing.

Description

technical field [0001] The invention relates to the field of light-emitting devices, in particular to a zinc oxide-based nanoparticle ink and an electroluminescent device. Background technique [0002] With the continuous advancement of technology, display devices are gradually developing towards thinner, higher color gamut, and more stable. As a self-luminous display device, quantum dot light-emitting diodes (QLEDs) just meet the requirements of next-generation display devices. QLEDs have the advantages of high color gamut and good stability. Zinc oxide is a group II-VI compound semiconductor material with a wide band gap and direct band gap. The band gap is 3.37eV at room temperature. -4 Ω / cm. Due to its excellent optoelectronic properties, its energy band position can be changed by doping different metal elements and ions. [0003] The existing zinc oxide nanoparticle electron transport layer is generally prepared by spin coating, but the spin coating method is not sui...
